date-format

问题 I have this in my XSD (please check code below): <xs:element name="Report_Date" type="xs:date" minOccurs="0"/> it is true that this field accepts only the date format yyyy-mm-dd and if any other format is given, JAXB unmarshalls it as null. But i want to validate the report_date field for incorrect format given in the request. Since this is an optional field, the application behaves same for even when the date not given and when the date is given in incorrect format. To make it simple, i want

问题 I created method for parsing a view different date formats during data import (400 K records). My method catches ParseException and trying to parse date with next format when it's different.

问题 I declared Calendar and SimpleDateFormat like this: calendar = Calendar.getInstance(TimeZone.getTimeZone("Malaysia")); final SimpleDateFormat sdf = new SimpleDateFormat("yyyy.MMMMM.dd hh:mm aaa"); or: calendar = Calendar.getInstance(TimeZone.getTimeZone("GMT+08:00")); Then I call this: sdf.format(calendar.getTime()); but result is not in correct time zone (+8 hours). What could be the problem? 回答1: Unless you are going to perform Date/Time related calculations, there is no point in

问题 I have two dates - a start and an end. I'd like to format them so that if the months match, they collapse to something like "20-23 AUG" and still format correctly if they break over the end of the month, like "20 SEP - 1 OCT". Are there any libraries out there for accomplishing this, or would I have to hand code rules for displaying ranges of dates using individual DateFormats? 回答1: Here's a solution using JodaTime, the best library for dealing with dates in Java (last time I checked). The

问题 I have a webservice with a method which is called via a xmlhttprequest object in my javascript.

问题 I have read date from XML which give me back string where the date is like DD-MM-YYYY . But when I want to add it to my core data database, SQLite sorts me that wrong so I have to convert it to date format or to string like: YYYY-MM-DD . But SQLite does not support either Date() or To_Date() functions. Can you help me? 回答1: You can use NSDateFormatter to format a date in Objective C. Here's a quick example which might not do exactly what you want, but should hopefully give some pointers: //

问题 I'm not that familiar with I18N in Rails so bear with me. Trying to set a custom date & time format: #config/locales/en.yml en: date: formats: long_dateweek: "%A, %B %d, %Y" time: formats: very_short: "%H:%M" But when I try to use them I just get the default formats: 1.9.3p194 :001 > Time.now.to_date.to_s(:long_dateweek) => "2012-08-22" 1.9.3p194 :002 > Time.now.to_time.to_s(:very_short) => "2012-08-22 16:12:47 -0700" Tried restarting console (and even the server) to no avail... What'd I miss

问题 I'm retrieving a datetime from a SQLite DB which comes out in the format... 2011-01-24 02:45:00 In C# I can simply use DateTime.Parse("2011-01-24 02:45:00").ToString("HH:mm") in order to get the string 02:45 Is their a way I can I do this in Android/Java?

问题 We all know the classic example of a date validation in the controller inside the initBinder method: @InitBinder public void initBinder(WebDataBinder binder) { SimpleDateFormat dateFormat = new SimpleDateFormat("dd.MM.yyyy HH:mm"); binder.registerCustomEditor(Date.class, new CustomDateEditor(dateFormat, true)); } But what is the alternative to support the new Java 8 Time API , where we need to replace DateFormat to DateTimeFormatter ? What tools Spring Framework provides for this? Thanks. 回答1
